CVE-2009-0217

The design of the W3C XML Signature Syntax and Processing (XMLDsig)
recommendation, as implemented in products including (1) the Oracle
Security Developer Tools component in Oracle Application Server 10.1.2.3,
10.1.3.4, and 10.1.4.3IM; (2) the WebLogic Server component in BEA Product
Suite 10.3, 10.0 MP1, 9.2 MP3, 9.1, 9.0, and 8.1 SP6; (3) Mono before
2.4.2.2; (4) XML Security Library before 1.2.12; (5) IBM WebSphere
Application Server Versions 6.0 through 6.0.2.33, 6.1 through 6.1.0.23, and
7.0 through 7.0.0.1; (6) Sun JDK and JRE Update 14 and earlier; (7)
Microsoft .NET Framework 3.0 through 3.0 SP2, 3.5, and 4.0; and other
products uses a parameter that defines an HMAC truncation length
(HMACOutputLength) but does not require a minimum for this length, which
allows attackers to spoof HMAC-based signatures and bypass authentication
by specifying a truncation length with a small number of bits.
